Geology field guide to Cougar Divide is published on-line

Mount Baker dominates the view from the luscious subalpine meadows of Cougar Divide. There are even some flowers left! Click to enlarge.

A self-guided field trip to the Cougar Divide trail is published on the Northwest Geology Field Trips blog. The trail follows a ridge crest just east of Skyline Divide, and is famed for meadows and expansive views. The field trip guide describes rocks of the Mount Baker volcanic field that are much older than Mount Baker itself. A dike crossed over by the trail  is the oldest dated rock in the MBVF, predating the Kulshan caldera by several hundred thousand years. A number of lava flow remnants are found along the way, including andesite, dacite, and rhyodacite. Get out and enjoy this geologic wonder before the snow flies!
